Lowery, D. D. (2014). Prayer. D. Mangum, D. R. Brown, R. Klippenstein, & R. Hurst (Eds.), Lexham Theological Wordbook. Bellingham, WA: Lexham Press. The OT uses four main words to refer to prayer and praying: פָּלַל (pālal, “to pray”), תְּפִלָּה (tĕpillâ, “prayer”), עָתַר (ʿātar, “to supplicate”), and תְּחִנָּה (tĕḥinnâ, “plea”). Other verbs for asking and pleading are used to express praying, including זָעַק (zāʿaq, “to cry out”), קָרָא (qārāʾ, “to call”), and שָׁאַל (šāʾal, “to ask”). Prayer is regarded throughout Scripture as a fundamental means of religious expression. This is because praying to God assumes in faith that he is powerfully willing and also graciously able to hear and respond to the prayers of his people—and further, that he chooses to work in and through these prayers. Thus, prayer is seen all through Scripture as both a wonderful privilege and also a solemn responsibility for God’s people. It follows, then, that prayer is utterly dependent on the revealed relational character of the God of the Bible, demonstrated most fully in the person of Jesus Christ in the NT. Jesus models in his earthly ministry the appropriate way to pray (Matt 6:9–13), and he assumes a mediatorial role in prayer (i.e., he teaches that the proper way to pray is “in my name”; John 14:13–14). Supplicants can become confident that God will hear their prayers because of what Jesus teaches his followers (Mark 11:24).
